Introduction: Male obesity is associated with an increase in estradiol (E2) and a decrease in testosterone (T). And, although sex steroids are associated with cardiovascular disease, direct effects on cardiac structure and function are hardly investigated in humans.Methodology: Twenty healthy men aged 20–40 years were randomized into two groups. One group was given an aromatase inhibitor (letrozole) only, thus obtaining a high testosteron...

Background and aims: The prevalence of sexual dysfunctions in people with diabetes is still debated and understudied in women. This study examines the prevalence of sexual dysfunction in men and women with type 1 or type 2 diabetes (T1D or T2D) and the associations with clinical and psychological variables.Methods: Adults with diabetes (n756) completed an online survey including questions on sexual functioning (adapted Short Sexual Functional Sc...

Objective: Testosterone levels are decreased in male obesity, the mechanism of which is incompletely understood. The aim of this study was to explore determinants affecting the feedback mechanism of the hypothalamic–pituitary–gonadal axis in male obesity and type 2 diabetes (DM2), such as aromatase expression and lipotoxicity.Materials and methods: Circulating levels of testosterone were quantified (<1000 h with LC–MS/MS) in 37 middle-...
